6/10 - 9/x = ?
9/x (simplify )
6/10 - 9/x = ?
3/5 (simplify this as well)
3\5 - 9/x=?
L (denominator) : 5
R (denominator): x
LCM (Least common multiple): 5(x)
Switch the denominators around
L(denominator): x
R(denominator): 5
3(x) - 45 / 5(x)
3(x) ➡3(x - 15)
3(x) - 15 / 5 (x) = ?
3(x) - 15 = ?
3 = ? (lets solve this problem)
x - 15 = ?
Now, lets add ( + ) the number 15 from each of the side sides of the problem that is shown above. (x - 15 = ?)
Finally, we get our result of this problem
x = 15
